Good evening William and welcome back!
Thank you for reaching out to us.
We are sorry to hear about the leftover undesired text creeping up on your single event view. Yikes!
I would love to help you with this topic.
It looks like you are using Avada.
This theme already contains some the Events Calendar customizations (as you have probably already found out).
For that reason, it is recommend to perform any changes (such as removing the featured image) in a Child theme. This way, you will not loose your changes every time there is a plugin update.
This also means that the approach suggested here: https://theeventscalendar.com/support/forums/topic/hide-featured-image-on-single-event-pages/ might not be the best one for Avada.
If I understand correctly, I believe some CSS would suffice.
Try adding the following CSS rule to your style.css file or in your Custom CSS metabox:
.single-tribe_events .fusion-events-featured-image {
display: none !important;
}
Let me know how that goes.
Best regards,
Geoff B.
